IMPROVEMENT IN SEDIMENTfAGITATORS FOR STEAM-BOILERS.

The Echedole referred to in these Letters Patent-and making part of the name.

. ment in an apparatus for preventing the formation of scale on the bottom of steam-boilers, and. consists in producing a circulation of the water in the lower portion of the boiler by means of an oscillating shaft' with movable vibrating wings connected therewith, arranged and operating as hereinafter more full-y described. The accom an du drawin is a )ers )eetive view of a a l a steam-boiler provided with my scale-propeller, a portion of the boiler being broken away to show the constrnction.

Similar letters of reference. indicate corres 'ioinliug parts.

A is the shell of the boiler.

B is the front head and .G is the back head of the boiler.

D is. a shaft uhicb passes longitudinally through the boiler, and is supported by the heads, as seen in the drawing, in stufiing-boxes, so that tight joints are formed around the shaft.

E are rods or'pins rigidly attached to i-the shaft,- hanging downward from its under side. u

i F are wings on the rods E, connected by sockets, so

that they have an oscillating o'r vibrating motion of themselves as the main shaft is oscillated.

g are wide slots in the sockets, and It are pins in the rods E. The width of the slots governs the amount of vibration of the wings, the pins actingas stops.

The shaft is oscillated in any convenient manner-so that the rodslfi describe about 0ne-'third of the inte-. rior circle of the boiler. Then this movement of the shaft takes place the wings F oscillate, and by their movements tend to force the scale, which may have, dropped from the boilr-flues or which may have been deposited by the water in the boiler,.to the end of the boiler, where it may, be, readily blown off orotherwise removed. The constant agitation produced by the movement of the wings near the bottom of the boiler would prevent the formation of scale on the bottom, if they exerted no propelling force; but when the scale and sediment are-forced to the end of the boiler. they are readily removed by means of either a hand-hole or-by blowing off from that end of the boiler.

Thisvis a simple and inexpensive device for preventing the formation of scale on the bottoms of steamboilers, and its advantages will be readily understood by engineers.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent- In combination with a. steam-boiler, the shaft 1), rods or pins E, and wings 1 arranged to operate substantially-as and for the purposes described.
